FIELD: engines and pumps.
SUBSTANCE: centrifugal compressor supplies to a circular diffuser, comprising a flange that passes in direction along the flow and along the crown of this compressor, and which is closed at the front side along the flow by a circular sheet element, which limits, together with the compressor crown, the first circular passage designed for passage of air flow taken at the outlet of the compressor, and limits, together with the flange of the diffuser, the second circular passage designed for passage of some air coming out of the diffuser.
EFFECT: reduced temperature of compressor crown and increased service life.
